Actually they put RC Reserves separately from RC under Distinctive Luxury section along with Bvlgari, Luxury Collections, and ... interestingly W Hotels
(RC is under Classic Luxury)

And about Singapore RC, I guess the issue is RCR promoting the property through RC Rewards spam mails
Like I said, while we all know very well that they not participated, I got feeling some members who didnt realise that might get upset.
Some negative reviews of that property is complaining about the non participation
